Answer:
Jeremiah travels at 26.667 mi/hr and Ermias travels at 18.667 mi/hr.
Step-by-step explanation:
Say Ermias' speed is 's' and Jeremiah's is 'v'
distance = rate * time
distance = ( v * time) + ( s * time)
v = s + 8
240mi = ( (s+8) * 8 ) + ( s + 8)
240 = (8s +64) + s + 8
240 = 9s + 72
240 - 72 = 9 s
168 = 9 s
18.6666667 = s
v = 18.6666667 + 8
v = 26.6666667
Answer:
33%
Step-by-step explanation:
48-15=33
33/100*100=33%
1)inside the triangule is 180º .There are 3 angules, one with 120º, theta and
angle ACB, lets call it x.
x + theta + 120 = 180
x + theta= 180-120
x + theta= 60
x= 60- theta
angle ACB= 60- theta
Morning = -2f
Afternoon = -2 + 9 f
Afternoon = 7f
